The objective of this study was to evaluate the potential health risk associated with exposure of dozer operators to whole-body vibration. Measurements were made on 31 dozers used in different surface mines in Turkey. Predictions of adverse health effects of vibration were based on the standards BS 6841:1987, ISO 2631–1:1997, ISO 2631–5:2004, and the EU Vibration Directive:2002. Operators experienced high and comparable levels of vibration acceleration and dose during all dozer tasks: pushing the material (DOZE), moving forward (FORWARD), moving backward (REVERSE), and ripping (RIP). Specifically, DOZE, FORWARD, REVERSE, and RIP showed high potential of adverse health effects in terms of vibration dose according to the worst-case axis and vector sum criteria and a moderate adverse health effect for acceleration according to the worst-case axis criterion. Operators of large dozers were exposed to lower levels of vibration. However, no statistically significant relationship between vibration exposure levels and the propelling mechanism and the service time of dozers, operator experience, operator age, and ground type was found.

本研究的目的是评估与推土机操作员暴露于全身振动相关的潜在健康风险。对土耳其不同露天矿山使用的 31 台推土机进行了测量。振动对健康的不利影响的预测基于标准 BS 6841:1987、ISO 2631–1:1997、ISO 2631–5:2004 和欧盟振动指令：2002。在所有推土机任务中，操作员都经历了相当高水平的振动加速度和剂量：推料 (DOZE)、向前移动 (FORWARD)、向后移动 (REVERSE) 和翻录 (RIP)。具体来说，打瞌睡，前进，倒车，根据最坏情况轴和矢量和标准，RIP 在振动剂量方面显示出很高的潜在不利健康影响，根据最坏情况轴标准，在加速度方面显示出中等的不利健康影响。大型推土机的操作员暴露在较低水平的振动中。然而，没有发现振动暴露水平与推土机的推进机构和服务时间、操作员经验、操作员年龄和地面类型之间存在统计学上的显着关系。
